We love Robert, AKA Mr. Sour on YouTube, AKA Roberts on Growdiaries. He’s a masterful cannabis grower. It is hard to believe he has only been in the game a couple of years if you look at his amazing grows! When not tending to his beautiful plants, he is always keen to lend a hand to growers on GrowDiaries or YouTube. Robert has answered thousands of questions; he is there to help others get the most out of their plants! A genuinely nice guy and an expert grower, he lends his expertise to AMS through a video series, blog posts, and more!
